Fix: User commands require channel layer lib

As channel layer is separated out from user layer lib, it
has to be manually included in libusercommands, as user
command handlers use channel layer API's

Tested-by:
1. Made sure that libusercommands are loaded on it's own
without any undefined symbol error.
2. ipmitool user list 1 works on host interface
